编译错误，求指正

[CYW]

编译以下语句时

volVectorField gradAlpha(fvc::grad(alpha1_)):
volScalarField mDot(this->mDot());
volScalarField vmDot(mDot*gradAlpha);

错误提示如下

no matching function for call to Foam::tmp<Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh> >::tmp(Foam::tmp<Foam::Field<Foam::Vector<double> > >)

各位大神有知道为什么的吗？

你的gradAlpha矢量乘以mDot标量应该是个矢量，为何用volScalarField呢

@东岳 Thanks!
